Subject: glsl: Eliminate constant_template5
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=abc81f788343e1780c21ec748153e7bb003cd7e0;p=mesa.git

glsl: Eliminate constant_template5

constant_template_common can now handle the case where the result type
is different from the input type by using type_signature_iter.
